Number of Beeps Troubleshooting Action
1, 2 or 3 Reseat the memory, or replace with known good modules.
4-7, 9-11 Fatal error indicating a serious problem with the system. Consult your system
manufacturer.
Before declaring the motherboard beyond all hope, eliminate the possibility of interference
by a malfunctioning add-in card. Remove all expansion cards except the video adapter.
If the beep codes are generated even when all other expansion cards are absent, the
motherboard has a serious problem. Consult your system manufacturer.
If the beep codes are not generated when all other expansion cards are absent, one of the
add-in cards is causing the malfunction. Insert the cards back into the system one at a
time until the problem happens again. This will reveal the malfunctioning add-in card.
8 If the system video adapter is an add-in card, replace or reseat the video adapter. If the
video adapter is an integrated part of the system board, the board may be faulty.
